BACKGROUND OF THE INVENTION

This Non-provisional application is a continuation of the Provisional Application No. 60/931,676 filed on May 25, 2007.

Originally this invention evolved out of a need for a mail recipient to be able to know just by looking at the his/her mailbox whether he/she has received mail or the like, in his/her mailbox without even opening the mailbox as well as to know if the mailbox door has been left open for any reason. A Mail Delivery and Mailbox Door Status Notification System, such as this invention, is greatly desired, since such inquiry can be made by the recipient even from a distance from where the mailbox can be clearly seen.

Previous designs have involved weight measuring devices, photo-electric cells, proximity sensors and flag systems to indicate that the mail has been delivered. The problem with the previous designs is that they either work only when mail of a certain weight is delivered or they involve elaborate systems and extensive mechanical parts to be installed inside the mailbox.

BRIEF SUMMARY

The present invention is based on the principal of an alarm system. A number of alarm systems have been introduced in all of the above designs, but none of the above designs addresses the concept used in the present invention as described hereunder.

This invention will enable a mail recipient to view the status of his/her mailbox as a result of an activity of delivery of mail or like items, or similar action that involves opening the mailbox door, and then closing the recipient's mailbox door, referred to here as the “Act of Mail Delivery”, or just opening the door and leaving it to remain open either inadvertently or as a malicious act. Previous designs involved weight measuring devices, photoelectric cells, proximity sensors and flag systems to indicate that the mail has been delivered in the mailbox. The problem with the previous designs is that they work only when mail of a certain weight is delivered or they involve elaborate systems and extensive mechanical parts, to be installed in the mailbox or they just send an alarm to remind the recipient that the mailbox door is open. The present invention addresses both needs of providing a visual indication that the said Act of Mail Delivery has taken place or if the mailbox door has been left in the open.

The current invention comprises of the following:

A first switching device, installed in the close proximity of the door of the mailbox, referred to here as the Switch 2, which is a “Momentary Push-Off” type switching device whose electrical contact changes state from an Open position to a Close position when the said mailbox door is opened; a second switching device installed in the close proximity of the door of the mailbox, referred to here as the Switch 4 which is a “Single Pole Double Throw” type switching device that changes the state of its electrical contact that is “Normally Close”, from Normally Close state to Open state and the state of its electrical contact that is “Normally Open”, from Normally Open state to Close state, every time the said Switch 4 push button is pushed due to closing of the said mailbox door; a source of electrical energy such as a system of batteries referred to here as the Power Supply; a timing device, referred to here as the “Timer” with its electrical contact, referred to here as “Timer Electrical Contact”, and that changes the state of its said Timer Electrical Contacts from “Open” state to “Close” state every time the said Timer is energized and times out and back to “Open” when the said Timer is de-energized, that said Timer Electrical Contact is electrically coupled to the said Switch 2; an electrically powered first lighting-emitting device that is mounted at the said Mailbox, referred to here as the Door Open Notification Light, that is electrically coupled to the said Timer Electrical Contact; an electrically powered second lighting-emitting device that is mounted at the said Mailbox, referred to here as the Mail Delivery Notification Light, that is electrically coupled to electrical contacts of the said Switch 4; a means of transmitting electrical signal between the above components of the electrical circuits installed at the said Mailbox and the said Power Supply.

Under normal conditions, the said Mailbox Door is closed, and the said Door Open Notification Light and the said Mail Delivery Notification Light are not energized. As soon as the said mailbox door is opened, the said Switch 2 shall change the state of its electrical contact from “Open” to “Close” state. Since the said Switch 2 electrical contact is electrically connected to the said Timer and the said Power Supply, this will complete the electrical circuit for the said Timer, making it to be connected to the said Power Supply. The said Timer shall be energized and if the said mailbox door remains in the “Open” position for a specific time, the said Timer shall time out and change the state of the said Timer Electrical Contacts from “Open” to “Close” state. The said Timer Electrical Contact is electrically connected to said Open Door Notification Light and the said Power Supply, therefore as soon as the said Timer Electrical Contacts are closed, electrical circuit for the said Door Open Notification Light shall be completed and the said Door Open Notification Light shall be energized to indicate that the said mailbox door is open.

If the said mailbox door remains in the “Open” position for less than the specific time, then as soon as the said mailbox Door is closed, the said Switch 2 shall change the state of its electrical contact back to the Open position thus de-energizing the said Timer. Also, as the said mailbox door is closed, the said Switch 4 shall change the state of its electrical contact that is “Normally Close”, from Normally Close state to Open state and the state of its electrical contact that is “Normally Open”, from Normally Open state to Close state. Since the said “Normally Open” electrical contact of the said Switch 4, electrically connects to the said Mail Delivered Notification Light and the said Power Supply, the said Mail Delivered Light shall be energized to notify the mail receiver that the mail has been delivered.

Now as the user opens the said mailbox door to retrieve the mail, the said Switch 2 shall change the state of its electrical contact from “Open” state to “Close” state again. Since the said Switch 2 electrical contacts are electrically connected to the said Timer and the said Power Supply, this will complete the electrical circuit for the said Timer, thus electrically connecting it to the Power Supply. The said Timer shall be energized and shall start timing. If the mail receiver leaves the said mailbox door open and if the said mailbox door remains in the “Open” position for a specific time, the said Timer shall time out and change the state of the said Timer Electrical Contact from “Open” state to “Close” state. The said Timer Electrical Contact is electrically connected to said Open Door Notification Light and the said Power Supply. As soon as the said Timer Electrical Contact is closed, electrical circuit for the said Door Open Notification Light shall be completed and the said Door Open Notification Light shall be energized.

If the user closes the said mailbox door shortly after opening it and the said mailbox door is closed within a specific time, as soon as the said mailbox Door is closed, the said Switch 2 shall change the state of its electrical contact back to the Open state, thus disconnecting the said Timer from the said power supply. Also, the said Switch 4 shall change the state of its electrical contact that is now in the “Close” state, from Close state to Open state and the state of its electrical contact that is now in the “Open” state, from Open state to Close state. Since the said Switch 4 electrical contact, that changes its state from Close state to Open state, is electrically connected to the said Mail Delivered Light and the said Power Supply, opening of the said Switch 4 contact shall cause the said Mail Delivered Notification Light to be de-energized. Once the user has closed the said mailbox door, at that moment the mailbox will again be in its normal state and the Mail Delivered Notification Light and the Mailbox Door Open Light shall remain in the de-energized condition until next time when the mailbox door is opened and the process explained above is repeated.
